Abstract After Yun Zhi mycelia or
fruitbodies are extracted by hot water and precipitated by alcohol, the Yun Zhi
mycelium extract (MWA) or Yun Zhi fruitbody extract (FWA) is obtained.
Then they are respectively developed by anthrone and phenolsulfate, and an
analysis is made by means of ultraviolet/visible light spectra. The
result shows that the maximum absorption wavelengths of MWA are 420 and 487nm
respectively and those of FWA are 671 and 486 respectively. After the
water solution of MWA is developed by ninhydrin, we see that its maximum
absorption wavelength is 586nm; but there is no obvious absorption of FWA.
Through a comparison of the infrared spectra of MWA and FWA, we discover
that there is an obvious absorption of MWA at 1380nm, while there is no obvious
absorption of FWA at that place. By phenol suplfate and Lowry methods to
determine the contents of polysaccharide and protein, we find that the glucose
contents of MWA and FWA are 36% and 48% respectively and the protein contents
are 33% and 21% respectively. With a rotatory instrument to measure the
specific rotatory power of MWA and FWA, we find that MWA is -0.04 and that of
FWA is -0.69. With DEAE-cellulose for column chromatography, we find that
the eluant of MWA contains 3 kinds of monosaccharide: galactose, mannose and
rhamnose while that of FWA contains only 2 kinds of monosaccharide: galactose
and rhamnose. The 0-2 mol of eluant of MWA contains 6 monosaccharide:
glucose, mannose, arabinose, xylose and rhamnose while that of FWA contains 5
monosaccharide: glucose, mannose, arabinose, xylose and rhamnose. The
main ingredient of FWA is not absorbed on DEAE-cellulose. Its molecular
weight is 6200 Da, while that of MWA is absorbed on DEAE-cellulose. its
molecular weight is 26000 Da.
